Which outcome results when chromatic dispersion widens pulses in a fiber-optic multiplexing system?

💡 Explanation

Chromatic dispersion broadens optical pulses because each wavelength travels at a slightly different speed; this **pulse broadening** leads to inter-symbol interference, therefore increasing the bit error rate rather than improving signal quality under ideal conditions or spectral efficiency.
